マイクロプロセッサによる坑内集中監視システム

抄録

Recently LSI technology has made a remarkable progress, in particular microprossesor has caused a technical inovation in every industry.
Ikeshima Colliery adopted a centralized underground mine monitering system based on microprossesors in 1978, for the purpose of modernizing safety installation, environmental and production control.
This report describes on the detail of system which is specialy arranged to meet the requirements of the underground coal mine.
The system consists of following consitituents by colour CRT display, analogue indicator and switch units; CH₄ gas density, air temperature, compressed air pressure, spray water pressure, cooled water volume, electric current and etc.; centralized monitoring, detection and remote operation of plans and safbty control devices.
